Thank you so much for responding!!! But I plan on putting on a new gas block so I can have room to put on my Madbull blackside on my outer barrel instead of the second piece of the outer barrel and because the front sight gets in the way of my scope. I was just wondering which gas block I could buy that would work to replace the front sight, compatibility wise and functionality wise.

...but I was not completely sure that it will work. Mainly I am concerned about it keeping the rails from wobbling. It doesn't have to be real steel either. Plus it looks like the pinhole for the pin for the gas tube might line up with the hole in the actual gas tube so it secures better.

Understood. The one I showed can be use to demonstrate a GB that would serve your purpose and also cover the grooves in the outer barrel that originally accepted the pins that secured the tower site. The one you posted will work, but it won't cover the old grooves. That would personally drive me crazy.

Are you sure that the new gas block will give you enough room to accommodate the reverse thread Mock Barrel Extension? It may get in the way and not allow it to catch the threads to secure on the outer barrel just as the front sight post gets in the way.

The most recent gas block I posted stays on the barrel via being tightened/clamped on by screws, not pins. The gas block is basically as long as the front sight post, give or take a little, so if will allow enough room to secure my Madbull Blackside flash hider. I can already screw on the flash hider about half way on and would be able to completely screw it on if not for this little part of the front sight that sticks forward at the bottom. Also, I read on another forum elsewhere that that gas block will keep the rails steady. I already ordered it so I'm confident it will work just fine. Thanks for responding!
